To explore the world of consumer genomics, Danish neurobiologist Lone Frank had her personal genome analysed. She found she had the so-called sensitive variants of the genes which can indicate a predisposition to psychological vulnerability. But there may be an intriguing upside. The orchid–dandelion hypothesis suggests that the genes and traits that underlie some of our greatest weaknesses, like despair and difficult behaviour, could also underlie our more positive aspects, like optimism and resilience. In this program writer David Dobbs and Lone Frank explore the expanding field of behavioural genetics and the complex interplay between our genes and our environment.
